hal_espressif repository was updated from esp-idf v4.2
to esp-idf v4.3 to allow latest Espressif chips integration.
As a consequence, it added a few changes in drivers
and peripherals. To maintain bisectability, changes in this
PR cannot be split. Here are some details:
wifi: update linker script by adding libphy and new attributes.
spi: update some APIs and fixed missing wait_idle check
west.yml: esp32: update hal to new version

Configures Segger RTT and SystemView data linker sections to DTCM by
default on i.MX RT SoCs if there is a zephyr,dtcm chosen node in
devicetree. This fixes a build warning in
samples/subsys/shell/shell_module for the mimxrt1170_evk_cm7 and
mimxrt1170_evk_cm4 platforms, which don't currently have a zephyr,dtcm
chosen node.
Note that there are runtime issues with Segger RTT and SystemView on
this board that need further debug, but submitting this patch now to
address nightly CI failures.

The PS/2 module in npcx provides a hardware accelerator mechanism
including an 8-bit shift register, a state machine, and control logic
that handle both the incoming and outgoing data. The hardware
accelerator mechanism is shared by 4 PS/2 channels. To support it,
this CL separates the PS/2 driver into channel and controller drivers.
The controller driver is in charge of the PS/2 transaction. The channel
driver is in charge of the connection between the Zehpyr PS/2 API
interface and controller driver.

rv32m1_vega don't boot due to device init ordering and changes with the
device model. The soc code is looking for a device pointer for the
intmux. Change to using DEVICE_DT_GET here as that will ensure we get
a valid pointer and by the time we need to utilize the pointer the
intmux driver will have been initialized and thus the device pointer
will be ready.
Also set BUILD_OUTPUT_HEX since we utilize openocd to flash and west
flash is looking for a hex file for openocd targets.

NPCX WIMU CR_SIN is used to wake up soc from NPCX sleep power state.
The wake-up IRQ enabled when UART init. It causes the wake-up IRQ to
generate many extra interrupt events, which causes the system too busy
to handle other events. This PR moves the UART wake-up IRQ enabling
from UART init to npcx_power_enter_system_sleep() to avoid the
interrupt storm.

Set the defalut value of SYS_CLOCK_HW_CYCLES_PER_SEC Kconfig option
from the Device Tree. The `clock-frequency` property of the DT cpu@0
node is a single source of truth defining the CPU frequency. This is
the value used e.g. by all Atmel drivers.
For Atmel SAM family CPU clock is currently the only supported system
clock source. Ensure that kernel understanding of the hardware clock
frequency is the correct one.

MPS2 AN521 is a dual (Cortex-M33) core where the two cores
have different capabilities. E.g CPU0 implements TrustZone-M,
while CPU1 implements the FPU. Therefore we introcude separate
Kconfig symbols for the two SoC variants, and use these to
select the different Cortex-M capabilities. We also update
the definitions of __MPU/FPU/SAU/DSP variant in soc.h to make
them get the value from the Kconfig settings, directly.

We should gurantee that we do not use SRAM during Zephyr early
boot, until SystemInit has returned. This commit aims to ensure
that SystemInit will be branched to, without first pushing args
to stack, even when no optimizations are selected. We chose to
define z_platform_init in assembly directly (instead of using
inline assembly) as it appears to be a cleaner design.

This is a follow-up to commit 60d9988401.
Add a third option for the HFXO capacitance that keeps the default
value of the XOSC32MCAPS register untouched. The message in the above
commit incorrectly claimed that external load capacitors for HFXO
(the reset value of the XOSC32MCAPS register) was the configuration
in effect before. In fact, the register value was modified during
the device trimming in the SystemInit() function to use the internal
capacitors, and that is the configuration required for proper RADIO
operation on nRF5340 DK, for instance.
